IMPROVEMENT IN MACHINES FOR DARNING STOCKINGS.

Specification forming part of Letters Patent No. 138,981, dated May 20,1873; application filed September 26, 1870.

To all whom it may concern:

Be it known that I, BENJAMIN ARNOLD, of East Greenwich, in the county ofKent and State of Rhode Island, have invented a new and Improved Machinefor Mending Stockings and other Fabrics; and do hereby declare thefollowing to be a full and correct description thereof, reference beinghad to the accompanyin g drawin gl making part of this specification,and to .the letters and numbers of reference marked thereon, similarletters and numbers being used in allthe figures to denote the samepart.

In the drawing, Figure 1 is a side elevation of the machine. Fig. 2shows a vertical section taken through the middle lengthwise of themachine. Fig. 3 shows a vertical crosssection of the standard A Fig. 4,face of the cam a. Fig. 5 shows the parts that move the levers g and hon the-periphery of the cams a and i. Fig. 6 is a top View of the headof the standard A, with the comb s and work :0. Figs. 7 to 12 showdifferent stages of the operation of the needle, looper, &c.

The nature of my invention consists mainly in using a semicircular combsliding in a curved race-way in an arm projecting out over a sphericalblock, which supports a needle with an eye near the point, which worksup through the stitches on the teeth of the comb, and in giving the comba proper feed-motion back and forward, &c.

The construction is as follows: A and B are two hollow standards,fastened to the bedplate 0. d is a shaft, turning in a bearing in theback of the standard B, holding the two cams a and ion its inner end,and ahandwheel, H, to turn it by on its outer end. 0 is the feed-lever,one end of which turns down and catches into the rack on the back of thecomb s, seen in section in Fig. 3. The other .end of this lever ispinned to the top of the lever g, Fig. 2, which communicates abackward-and-forward and upward motion to it from the cam a, the springt pressing it down. 70 is the looper and casting-elf lever, one end ofwhich passes out of an opening in the arm D, so as to operate on thecomb outside. The other end of the lever is connected to the top of thelever h, which communicates a backward-and-forward and downward motionto its outer end from the groove in the cam i, the spring a, Fig. 1,pressing it up. The comb s is held on a flange on the arm D, the fronthalf of the arm shutting down on it, so that the back row of teeth areinclosed in the arm with the feed-lever, and the outer row of teethstand out in front of the arm. A plate, 42, is placed in the head of thestandard A, on which the needle-block 0 slides up and down, guided bytwo screws in a slot in the plate. (See Fig. 3.) A lever, O, is hung ona pivot underneath the bed-plate G, which communicates motion from apin-in the face of the cam a to the needle-block 0, one end of the leverbeing connected to the pin by the rod b, and the other end to the blockby the bar a.

The operation is as follows: The stocking is drawn under the comb s andover the standard A, until the place to be mended is just under the edgeof the comb, so that when the needle m rises it will pass up through theedge of the stocking on the front side of the hole, and make the firstrow of stitches or loops through it. Then, by turning the hand-wheel H,the needle will be pushed up through the work, carrying with it the yarnp, and as it descends the looper It will be thrown forward and down,holding the loop, as seen in Fig. 11,

so that the comb, by sliding one tooth by the needle, will catch theloop and hold it as the needle draws down. In making the first row thereare no loops on the comb to be cast off, but in after rows when theneedle rises it comes up through the loop or stitch on the tooth infront of it, and the looper It moves down and forward until its end isunder the loop the needle is in, when, as the needle rises further, thelooper rises to and casts off the loop from the point, so that it hangsaround the needle, (see Fig. 8,) and as the needle again descends a newloop or stitch is deposited on the tooth of the comb, as above describedin making the first row. When a row has been knit across the hole, byreversing the motion of the hand-wheel, a row back to the other sidewill b e made, a part of cam a, marked a, Fig. 4, being made" "so as tofall back and bringthe feed-motion right as to time in turning bothways. The cam i is attached to this piece a, and falls back in the sameway for the same reason.

-It will be seen, by reference to Fig. 2, that the levers g and h haveslots in the middle. These are provided to let the levers e and 70 riseand fall, which motions are given by projections on the cams.

Having thus described the construction and operation of my machine, whatI claim as my invention, and desire to secure by Letters Patcut is- 1.The comb s, in combination with the needle m, constructed and operatingsubstantially as and for the purpose set forth.

2. The combination of the feed-lever 0 with the comb s, substantially asspecified, and for the purpose set forth.
